To give you a comparison, my 60ft times on all my 11.6 & 11.7 runs were between 1.77-1.79. I feel i would have to get some lightweight rims to reduce the 60ft time with that setup, or get tyre pressure dialed in a bit more.
A 1.9 is pretty good! Maybe ask Trebila to tweak your tune to give you a little more down low for the 60ft

Yep thanks for the tips mate. I think having 19" rims on is not helping lol. Yeh once the new turbos go on will be tuning further

Well you have the MPH for an 11.8-11.9 or so, its all in the fine tuning now : )
P.s, order a BMS kickdown blocker, there like $10, its worth having a try launching from 2nd. My car was slipping under the torque load on the BMS flash, MHD will be fine as David can modify the tables

[tawfeeqh]

12.14@ 118.1 mph 1.9 60 ft
12.26@ 118.3 mph 2.0 60 ft
12.29@ 118.5 mph 2.1 60 ft

I need to bloody improve on launching and getting 60 ft down to 1.8. Prob need better tyres/ semi slicks on 18".

I think i might call it a night lol

Kickdown block can be done very easily in the flash now.

Well at least your fairly consistent with the MPH. Dont bother with semi slicks, get a good pair of MT or Hoosier's, there the same price as semi's anyway. Your best to run some 17's that way you can get a little bit more sidewall on your tyre

[bmwheath]

How much fuel was in the tank? Weight reduction is your next option. Did you log any of the runs?

Had one more run for the road lol

12.09@118.55 mph 1.9 60ft - shifted a bit early 2nd to 3rd but still managed a decent time.

Yeh might just get some 17s and throw DRs on them. Will prob be a better option for when I install the rr700s.

Fuel was 3/4 tank full.

I had the tablet connected but i think I only managed to get one log as I forgot to press start in one of the runs (got nervous at start line lol) then bloody ran out of battery in another run lol

Haven't gone into limp mode but I think im stressing my hpfp out. AFRs still look fine and stays between 12.4-12.7 and stft also within tolerance. Might throw in a fresh one when installing the 700s.

Remember shifting at 6000rpm is more like 6600rpm, try closely watching your tacho needle next time you go down the track you will see what i mean.
Whats your drag setup? How much fuel? Whats your average ignition at in the logs? A bit of octane may help. Passenger seat removed? What tyre pressure? You getting any wheelspin? What suspension are you on?

Sorry didn't see all your questions

- 3/4 tank fuel
- not sure about average ignition
- no lsd with stock m sport suspension
- 265/30/19 rears with kumho ku39 @ 32psi
- first level dtc off i.e didn't press for 5 sec to turn things off completely
- Not much wheelspin, hooks up well, but im also not going pedal to the metal when launching
- full street trim (with baby seat lol)

I generally run with 1/3 tank of fuel. Every 10L of fuel weighs 7.4kg. A LSD and Drag radials will make a big difference in your 0-60' times. I would turn the DTC completely off. I change 1st to 2nd at 5,000 rpm by the OEM tacho and it is still reaching 6,800rpm in 1st. If you can data log a couple of your runs, you will find out what revs you are launching at and what rpms you are reaching on the gear changes.

Cool cheers for the tips!

I have two logs from the run I think, so will check it out. Next time will try around 1/2 tank

The trap speed definitely there for a 11 pass

If you have a look at Dragtimes.com and compare your speeds with those listed, you will find that the cars that are pulling 118mph are achieving times between 11.7 to 11.8s but have 0-60' times of 1.7-1.8s.

Line lock and LSD.

yeh and Heath also has pulled those times too. The key is improving the 60 ft to 1.7-1.8

yeh will look into that and try and install over the next 6 months

There's a dude in the USA who's bought a set of 15' rims to fit drag slicks to, with a rear brake 'downgrade' to accommodate the 15' rim.

By memory he mentioned AD engineering offer this kit, this is what will be interesting to see how it transpires in terms of 60ft times and if the baggier sidewall causes any issues on the big end in terms of floatiness...

Yeh might try 17s first and some Hoosiers. If I get that 60ft to 1.7-1.8 will crack 11.7-11.8.

I was running 1.9 and hit 12.09@118.55mph

Or maybe I won't kill myself trying coz after i install the rr700s will see 11s pretty easily lol. That said will still need some DRs or Semis

[Fundguy1]

16s or 15s are the way to go. That's what all the vette guys do. You use a 328i setup rear to fit them. You can fit16s with a grinding wheel on 335i calipers too.

What coupes said. Run 1/3 to 1/4 of a tank, trust me you wont run out of fuel or surge, your only flooring it for 11 seconds a couple of times. I remove a few easy bits to reduce any weight like the tool kit, boot trims, back seat bottom, engine bay cowl & cover, maybe a few other bits i cant remember. Doing this and having minimal fuel in the tank can save you around 50kg's! I have to do this as i weigh 100kg's. Check your logs to see if you are pulling any timing on the runs as you may be able to bump up the octane and get a few extra hundredths/tenth of a second?? Get some slicks & lightest rims you can afford. An 11 is there for the taking. Or just switch back to BMS E85 BEF MAP7 and run mid 11's like i was

Was that "LostMarine" from memory?? He was running like 11.1 on stock turbos. High sidewalls and low tyre pressure will definately cause floatiness no matter what, the 15's can get sketchy if going above 28inch so we should be ok if your a competent driver. Gotta risk it to get the biscuit though
